An official report is set to reveal that British spies failed to do enough to track and monitor the killers of Fusillier Lee Rigby.

MI5 will face criticism from the Parliamentary Intelligence and Security Committee today, claiming it could have given more priority to watch Michael Adebolajo and Michael Adebowale, in run up to the soldier's murder in May last year.

The Independent's chief political commentator John Rentoul explains more.

The findings will also confirm that the security services had attempted to recruit Michael Adebolajo.

Lee Rigby was killed in a brutal attack outside Woolwich barracks in May last year.
